suppose you walk on a slope. There you can place your foot at any height. So the height could be continuous.
But in case of steps as you climb up, then you would place your foot only at some heights. No continuous values but only descrete values.
In the same manner electric charges are available only in descrete values. Hence there is a basic ie fundamental ie elementary charge.
Its value is found as 1.6 x 10-19. The unit for electric charge is coulomb.
This is what we call quantization of electric charge.
Same way in case of radiation, the energy of radiation is also emitted only in descrete values. Hence such packets of energy is known as quantum of energy. The energy of quantum is given by hv. h is Planck's constant and v is the frequency of radiation.
When we purchase bun in a bakery we cannot claim for 1/2 or 3/4 or 1/5 of bun. The shopkeeper would see us in a differnt way. So bun is already quantized.
Quantization range refers to the range of values that can be represented by a quantization process. In digital signal processing, quantization is the process of mapping input values to a discrete set of output values. The quantization range determines the precision and accuracy of the quantization process.
Mid riser quantization is a type of quantization scheme used in analog-to-digital conversion where the input signal range is divided into equal intervals, with the quantization levels located at the midpoints of these intervals. This approach helps reduce quantization error by evenly distributing the error across the positive and negative parts of the signal range.
If the sampling frequency doubles, then the quantization interval remains the same. However, with a higher sampling frequency, more quantization levels are available within each interval, resulting in a higher resolution and potentially improved signal quality.
Quantization of energy typically only becomes noticeable at very small scales, such as the atomic and subatomic level due to the principles of quantum mechanics. At larger scales, such as in everyday observations, the effects of quantization are averaged out over many particles and energies, making them appear continuous.
A quantization codebook is a set of codewords that are used in quantization, a process that involves mapping input values to a limited set of output values. The codebook contains the predefined values to which the input signal will be quantized to, based on minimizing the distortion between the original and quantized signals. It helps in representing continuous values by discrete values.

The ideal Quantization error is 2^N/Analog Voltage
There are two types of quantization .They are, 1. Truncation. 2.Round off.

Quantization noise is a model of quantization error introduced by quantization in the analog-to-digital conversion(ADC) in telecommunication systems and signal processing.
quantisation noise decrease and quantization density remain same.
You get Jaggies
Vector quantization lowers the bit rate of the signal being quantized thus making it more bandwidth efficient than scalar quantization. But this however contributes to it's implementation complexity (computation and storage).
assigning discrete integer values to PAM sample inputs Encoding the sign and magnitude of a quantization interval as binary digits
If the sampling frequency doubles, then the quantization interval remains the same. However, with a higher sampling frequency, more quantization levels are available within each interval, resulting in a higher resolution and potentially improved signal quality.
